Soak the hell out of it with wd-40 or similar, be sure to get the captured nut as well as possible. then use a long breaker bar on the socket. use 'gentle force'. If you twist the head off the bolt, it can get real complicated fast (like cutting the exhaust brackets off,taking the 'capture' out, and trying to push the nut/bolt out the front). Maybe a little heat too but I wouldn't use an open flame, maybe a heat gun?

as jedi says , there a beggar to get too , sime66 had this last year ,will try n find the thread n link it to ya, a search for px exhaust bolt should bring up the various dodges/methods to try , worst case its lump out n drill the bolt out , an whatever you do cover the bolt in copper grease when it goes back in .

Indeed I did, and here's the link: vespa.proboards.com/thread/3899/headless-exhaust-swing-arm-boltMore important though, is what jedihunter said about taking care with the bolt-head if you still have it; my exhaust was fitted 'by others' (since sacked) and I only discovered the seized bolt - with no head - when I went to change the exhaust, and at that point, as mentioned above, the job does indeed get real complicated fast. When you have fixed it, and you'll only have it happen once to learn to prevent it, it's plenty of copper grease when it goes back in, and a regular loosening and re-tightening, just to keep it moving, as part of routine maintenance now for me. An experience not to be repeated. |

i think i mentioned it in simes thread above ,but had same deal on a friends scoot ,head snapped of , i had to drop front of engine an cut old exhaust off ,it was missing the downpipe n no lose , then unscrew the captive nut after removing cage ,lots of heat n wd40 used, put new exhaust on with a ordinary nut an no captive nut/cage , treating the headless bolt like a stud ,bit of a bodge but still going strong today ,ok, H

Yes you did, H; sadly the damage was done before the benefit of your advice. The point with nik's is that he hasn't lost the bolt head yet, so as jedihunter said 'gentle force' first - head and WD-40 soaking, to avoid escalation of problem if possible; it probably will be a full-on palaver, but if you can get it moving with the head still on it's going to be less of a drag.

thanks guys - the nut end is still on BUT it is beginning to round at the edges - ill have a go with wd40 and a large bar - but if all fails drilling has to be the way then ?

Get the engine out and heat it up, while there is still a head on the bolt!

as guru says ,theres a million dodges an timesavers , but i often find that gettin medieval on its ass from the get go actually saves time in the long run , an if it goes pear shaped you'll need the lump out to sort it , or cut the cage off the exhaust undo or split the square nut an copy my above bodge if scoots needed back on the road asap, H

just gone through the same procedure with reference to exhaust bolt removal.never thought it would happen took a blade of a hacksaw and removed nut soaked bolt regularly for the next three days with wd 40,still no go used a six sided socket on a strong arm no!,only way now to apply heat shielded the area where heat to be applied applied with blowtorch gently gently strong arm brought into action and a gentle pressure to start off more heat more pressure and crack it gave up ( hip hip who bloody ray ) more heat and backwards and forwards it gave up and i was able to remove it.bolt replace with stainless steel nut and bolt with lots of copper grease job done but not a nice one if you come across this problem  |
